Observations and opinions of a British physicist in Japan Scotland
Mobile phone blogging from the stunning tropical island of Zamami. Went snorkelling round the coral reef and saw colourful fishies like I wold expect in a rich person's aquarium. Sadly phone camera doesn't work underwater, at least not for very long.
Pair production in superconductors
Authors: J. E. Hirsch
Comments: better safe than sorry - experimentalists please take note
Subj-class: Superconductivity; Strongly Correlated Electrons
We show that an alternative theory of superconductivity recently proposed (theory of hole superconductivity) leads to the surprising consequence that real electron-positron pair production will occur for superconductors larger than a critical size. We discuss the expected magnitude of the effect and suggest experimental ways to verify it. Urgent attention to the possibility of harmful gamma-radiation being emitted from superconductors out of equilibrium is called for.

I'm in the mountains of northern hyogo playing ultimate in the rain. Fortunately unlike England that doesn't mean its cold. Go Kinki Trolls!
